Every company in your inbox also has a bar. This bar either has the colour red, orange, yellow or green. This is the lead score and it shows how interesting the company is for you.
The lead score is based on a number of factors. It looks at the number of pages a lead has visited, how many visits a lead has made to your website and for how long a lead has been on your website.
The greener the lead score the more interesting the company is.
